Inputs/Outputs
Selector String
—
Selector String specifies a selector string comprising of the signal name, result name, and user number. If you do not specify the signal name, the default signal instance is used. If you do not specify the result name, the default result instance is used. The default value is "user0". Example: "user0" "signal::sig1/user0" "signal::sig1/result::r1/user0" "result::r1/user0" You can use the RFmxWLAN Build User String VI to build the selector string.
